INDOOR UNIT OPERATION WHEN CONNECTED TO
MULTIPLE UNITS
Group combination
When executing group control on multiple unit system
Group control of up to 8 units is available with single remote controller.
Use wired remote controller for group control.
• For wiring and wiring procedures for individual system (using the same refrigerant), refer to the installation manual
of each combination.
• Wiring between systems should be done by the following procedures:
Connect the remote-controller terminal plate (A, B) on the indoor unit, to which the remote controller is connected,
to the terminal plate (A, B) on each of other indoor units by linking them with each other with remote controller wiring.
• Automatic address setting commences when the power is turned on. After 3 minutes, "SETTING" will be indicated
on the display panel to show that the address is being set.
Automatic address setting takes approximately 5 minutes until completion.

• Length of wires for remote controller (L) should be 200 m (in case of using wireless remote receiver), 300 m
(another controller) or less.
• Length of wires for remote controller should be 200 m or shorter in total (i.e., L1 + L2 +.... Ln).
Some group control system configuration requires manual address change after automatic address setting.
• System configuration that requires address change is the combined system where twin and triple system of
